I am sorry to hear you are having issues. The first thing I would ask, did you test the cable before making it a permanent installation? Did you notice that the cable is directional where the Inline IC extender is closer to the Display/TV/Monitor? The reason the audio might be working is that the audio is bi-directional and the cable may be installed backward where the video would not work but the ARC would. Especially since we use 100 pure copper for both the data and audio cables. The three Video bundles have to be 100% already.
